On top of the world in Europe

The Cube, a unique, temporary "pop-up" restaurant that first surfaced in Brussels and Milan, is making its way through Stockholm and London. At every stop, this whimsical, one-of-a-kind dining experience is commanding attention from foodies.

In each city, The Cube is erected on top of a well-known European landmark with spectacular views and remains there for at least three months. Designed by an Italian architectural firm, the minimalist, 1,200-square-foot glass and aluminum structure is visually provocative.

The setting and price point (take a deep breath — about $250 and $400 per person for a fixed-price lunch and dinner, respectively) allow award-winning chefs to show off with flair. In the glass-walled dining room, 12 to 18 guests are seated at one long table. The open kitchen and intimacy make for fast friends.

The Cube is sponsored by 90-year-old Electrolux, a Swedish company known primarily in the U.S. for vacuum cleaners, but a venerable supplier of restaurant equipment in Europe.

Two Cubes were built for simultaneous use. Currently they are perched on the Royal Opera House in Stockholm and overlooking the Thames River in London.

Having served 4,000 guests since opening in June, the London Cube has been extended until Jan. 1. The Stockholm Cube will close Oct. 21. Electrolux is hush-hush about the next cities to host these over-the-top pop-ups.
